INVALlo-BEDSTEAD.

SPECIFICATION forming part of Letters Patent N o. 703,535, dated July 1, 1902. Application filed .Tune 27, 1901. Serial No. 66.277. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, JAMES D.l CAMEIELD, a citizen of the United AStates,' residin g at Skilesville, in the county of Muhlenberg and State of Kentucky, have invented certain new and useful AImprovements 'ininvalidiBedsteadsg Vand I do declare the following to be a full,

clear, and exact description-of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to invalid-bedsteads.

The object of thelinvention is to provide a bedstead'of'this character which'shallbe simple of construction,-durable in use, comparatively inexpensive ofproduction, easily oper-V appended claims.

In the accompanying drawings, Figure 1 i a side view of the bedstead, showing in dotted lines the head-section adjusted to an inclined positionand the foot-section adjusted to an arched position. Fig. 2 is a similar View of a portion-of the bedstead, showing in 'full lines the outer end ofthe foot-section swung down to a point contiguous-to 'theoor and-showing in dotted'lines said end swung upwardly above the side rails-of-the bedstead. Fig. 3 is a fragmentary top'plan View.' Fig; 4 is a fragmentary View looking at the inner side of the side rails of the bedstead. Fig. 5 is a rear view of the 'headboardof'-thebedstead, and Fig. 6 is an outer view of the footboard of the bedstead. Fig. 7 is a detail perspective View of the rock-shaft for adjusting the hinged Slat-rails. Fig. 8 isa detail view of a fragment of abcd-rail, showing the keyhole-slotv for the headed end of they rock-shaft.

In the drawings, 1 denotes the side rails of the bedstead, each rail consisting of two members 2 and 3, hinged together by a pivot 4, which permits of the upward swinging movement of the members 2. Secured to the foot end of the rails is a footboard 5, the legs 6 of 5o which are mounted upon casters 7.

8 denotes the headboard, consisting of the posts 9, each of which consists of two separate parts 10 and 11. To the parts 10 are xedly secured the side rails 1, and the lower ends of the parts 11 are secured to casters 12.

13 denotes twobars, each of which has one end secured by a dowelfpin 14 to the part 11 Aof the post and has its its other end engaging antifriction-rollers 15, carried at the lower ends of hanger-brackets 16, secured to the part 3 of theside rail.

17 denotes slat-rails at each side on the side rails and connected togetheragainst spreading by slats 18, the ends of Awhich are formed with dovetailed tenons 19, which fit similarly shaped seats 20, formed-in the upper sides of said-slat-rails. Each rail consists of three parts or sections 2l, 22, and 23, hinged together at 24 and 25 on aline with the pivot 4.

26 denotes a shaft which is secured to the headboard on its outer side near its lower end and is provided with one or more hand-wheels 27, a sprocket-wheel 2S, andgone or more Vratchetwheels`29 engaged with one or more p'awls 30.`

31 denotes two vertical standards secured to the lower sections 11 of thel posts of the headboard and connected at their upper ends by a cross-piece 32.

33 denotes a hanger adjustably secured to the cross-piece 32 and supporting a sprocketwheel 34, which is connected to the sprocketwheel 2S by a sprocket-chain 35, which is connected to the headboard 8 by a bolt or similar fastening device which is attached to a plate 36, secured to said headboard, and has its head projecting through one of the links of the chain.

By rotating the hand-wheel 27 the sections 21 of the slat-rails, together with their slats and the headboard, will be elevated to the position shown in dotted lines in Fig. 1, and while this elevation is taking place the sections 11 of the posts of the headboard are moving toward the posts 6 of the footboard,

being guided in their movement in that direction by the bars 13 engaging the antifriction-rollers 15 and by the casters :12, which While being free to rotate in their brackets have their brackets fixed to the post against any swinging movement. When it until said section is lowered to a horizontal IOC) position, and the lower ends of the post-sec tions 10 seat upon the upper ends of the postsections 11, in which position the dowel-pin 14 extends into sockets 37 of the post-sections 10.

38 denotes a rock-shaft extending transversely of the bedstead under the Slat-rails 2 and having at each end a reduced neck 39 and an enlarged head 40, which projects into a keyhole-slot 41, formed in the plate 42, secured to the inner face of each of the sections 3 of the side rails of the bedstead. The shaft 38 is provided with crank-arms 43, which project under the Slat-rails 22, and is also provided with an operating-handle 44, by means of which it may be rocked to elevate the cranks,and thereby elevate the railsections 22 and 23 to an arched position, as shown. When in this position, it is desired to support the parts, and to that end I provide rods 45, hinged to the Slat-rails 22 and adapted to engage racks 46, secured to the side bars of the bedstead. In this adj ust= ment of the sections 22 and 23 some means must be provided for supporting the outer end of the section 23. I therefore provide rods 47, which have bent ends 48, which project into seats 49, formed in the parts 3 of the side rails of the bedstead. Upon these rods the outer or lower end of the sections 23 are supported in an arched position. If it be desired to lower the section 22, the swinging rods 45 are withdrawn from their racks and the parts allowed to fall to a horizontal position. If it be desired now to lower the section 23 to a point below the horizontal plane of the section 23, the bent ends 48 of the rods 47 are forced further into their seats 49 in the side rails of the bedstead, thus freeing said rods 47 from the side pieces of the section 23 and permitting said section to lower. This section 23 may be supported in its lowered position by ropes 50, which are joined to a ring 51, which connects with a rope 52, which leads to and is connected to the windlass 53, mounted in suitable bearings 54, secured to the footboard, and provided with a crank-lever 55 and a ratchetwheel 56, said ratchet-wheel being engaged by a liolding-pawl 57.

Any suitable means may be provided for the purpose of operating the rods 47 to move them into and out of engagement with the side pieces of the section 23 for the purpose of supporting and releasing said section; but those shown are preferred, and consist of crank-levers 58, pivoted to studs 59, projecting from plates 60, secured to the footboard and connected at their lower ends to arms 6l, formed on the ends of the rods 47. By elevating the levers 58 the bent ends 48 of the rods 47 will be shifted to bring the rods 47 under the side pieces of the section 23 to support said section. When in this position, the crank-lever 58 may be held by buttons or similar devices 61. The windlass 53 may be employed for holding the section 23 in its inclined position above or below the side pieces of the bedstead.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and details of construction may be made with-v in the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In an invalid-bedstead of the character described, the combination with the hinged side rails and the headboard connected to the free upper ends of the side rails, and means for supportingr the lower ends of said side rails, of bars slidably connected with the lower sections of the side rails, posts connected to the upper ends of said bars, and means for elevating the headboard and the side-rail sections to which it is secured, substantially as set forth.

2. In an invalid-bedstead of the character described,the combination with the side rails, each of which consists of a foot and head member pivoted together at their inner ends, a footboard secured to the free end ofthe foot member, and a headboard secured to the free end of the head member, of bars slidably connected to the foot members and underlying and parallel with both the foot and head members, and posts secu red' to the outer ends of said bars and adapted to support the headboard and outer end of the head members of the side rails, and means for elevating the headboard and head members of the side rails, substantially as set forth.

3. In an invalid-bedstead of the character described, the combination with the foldable side rails comprising head members and foot members, the head members of the side rails being provided with a headboard and the foot members of the side rails being provided with a footboard, of bars underlying and engaging the lower edges of the members constituting the side rails, brackets secured to the foot members of the side rails and provided with frictional rollers upon which said bars are supported to slide, posts secured to the opposite ends of the bars and adapted to support the headboard when in its normal position, and means for elevating the headboard, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JAMES D. CAMFIELD.
